The sea west of Spitsbergen; the oceanographic observations of the Isachsen Spitsbergen Expedition in 1910 . current should have been, in1910, C. warmer than in 1899, and C. warmer than in mean temperature of Mohns Stats. 306 and 308 is ° C, thatof Isachsens Stats. 3 and 4 is ° C, and that of MakarofFs Stat. 33is ° C. The first four of these were south of the last (see Fig. 21)but taken earlier in the season. If we compensate for this, the meantemperature of Mohns stations should be ° G, and of Isachsens sta-tions C. The current in 1910 should consequently have been than in 1899, and C. warmer than in 1878. The mean temperature of MakarofFs Stat. 16 (of August 15th, 1899)was C. That of Isachsens Stats. 10 and 1 1 (of June 27th, 1910)was ° C, which, owing to the earlier season, should be increased C. The current should accordingly have been C. warmer in1910 than in 1899.

THE SEA WEST OF SPITSBERGEN. 35 200 Stats. 6 and 77 ma} seem toindicate thatthis part of thecurrent wasmuch warmerin 1898 than in 1899, butsomewhat colder than in higher temperature of theupper strata above 50 metresis evidently due to the muchlater season. But as the con-ditions change rapidly in theseshallow waters no certain con-clusions can be drawn fromso few observations. During the Andree Expe-dition of 1896, Prof. Arrhenius took four seriesof temperatures on the Bear Island Platform(Fig. 21, A7—Aio), on August 22nd and 23rd,1896. These stations are farther east and inshallower water than Isachsens Stat. 1, HjortsStat. 62, and Makaroffs Stat. 5; so that theyare not comparable with these. ArrheniusStat. 7 was his deepest; its vertical tempera-ture curve is represented in Fig. 24, but nocertain conclusions can be drawn from it. Itmigh
